| description | The invention discloses a hydraulic oil cylinder with long service life, and particularly relates to the technical field of hydraulic oil cylinders. The hydraulic oil cylinder comprises a right ring and an oil cylinder, wherein one end of the right ring is fixedly connected with a piston rod; a sealing ring is fixedly installed inside the oil cylinder; one end of the piston rod is attached to a piston; a piston shaft is fixedly installed inside the piston; an air inlet valve is arranged at the top end of the oil cylinder; an air outlet valve is arranged at the top end of the oil cylinder; and one end of the oil cylinder is fixedly connected with a left ring. According to the hydraulic oil cylinder with long service life, the piston shaft and the piston rod are tightly connected together through the arrangement of the piston shaft, a limiting assembly and a U-shaped assembly, the good limiting effect is achieved, the situation that the piston and the piston rod are not concentric in the mechanical movement pro |
